A passive overflow device for draining away head water standing above settled sand in a loading space of a hopper, wherein the passive overflow device extends along a longitudinal axis and includes: an inlet for taking in the head water; an outlet section having an outlet for opening out in the outboard water and which outlet is level adjustable into an active position wherein in use, the head water is delivered proximate the sea bottom; a conduit which extends along the longitudinal axis of the passive overflow device and which conduit fluidly couples the inlet and the outlet; and a supporting structure for coupling the overflow device with the loading space of a hopper, wherein, the outlet section includes an flexible portion proximate the outlet for preventing mechanical overload to the supporting structure when the outlet, in use, in its active position accidently abuts the sea bottom. |
